Gibbsite and Moissanite Chemical Formula
While comparing Gibbsite and Moissanite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Gibbsite and Moissanite chemical formula.

Gibbsite and Moissanite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Gibbsite and Moissanite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Gibbsite and Moissanite Optical Properties during the identification of gemstone. Specific gravity of Gibbsite is 3.17-3.24 whereas that of Moissanite is 3.17-3.24.
